ext2fs can't read symlinks

[Roger Hammerstein]

Hello.
I have a 2tb Seagate ST32000542AS (4k sectors)
with ext2fs that can't seem to read symlinks
from a linux-created ext2fs.  

I was rsync migrating files from a linux machine to this freebsd, and booted
an Ubuntu livecd to partition the disk and make the filesystem.  I partitioned
it into a 1.5tb partition and a 500 gig partition.


I am getting read errors on some symlinks on an ext2 filesystem, but they
read fine when I boot an Ubuntu live cd.  Smartctl shows no errors for the disk.
The filesystem also checks fine with fsck.ext2fs on both freebsd and Ubuntu live cd.


I rebuilt the kernel earlier this week.

Here's the error:

Feb 10 13:08:23 butter kernel: g_vfs_done():ada2s1[READ(offset=-963020587008, length=4096)]error = 5

The negative offset looks wrong, and the length is always 4k multiples.

ls -la in the problem directory shows:

There's a symlink named JKL pointing into the 'JKL [123456]' directory.

a 'stat *' in the directory shows the link::

100
 75431952 lrwxrwxrwx 1 (1008) (1008) 301758464 83 "Feb 10 12:35:36 2011"

"Dec 31 18:59:59 1969" 4096 8 0 JKL [123456]

You can see that the symlink doesn't display the usual "-> " and the target of the symlink in the ls or stat output.

What other commands could I run to provide more information on this?
Other symlinks on this filesystem also generate the g_vfs_done errors.

Thanks.
